Objective To assess the efficacy of proton pump inhibitors for preventing post-endoscopio retrograde cholangiopancreatography (post-ERCP) pancreatitis and hyperamylasemia. Methods A total of 250 patients, who underwent successful ERCP, were randomized into control group (n = 126) or treatment group (n=124) after ERCP. All patients received octreotide, the patients in treatment group received omeprazole 40 mg i. v. every 12 h; while the patients in control group received same amount of normal saline. The serum level of amylase at 4, 24 h and TNF-a were determined and the incidence of post-ERCP pancreatitis was documented. Results There were no differences in age, sex and proportion of therapeutic procedures performed between the two groups. The serum amylase and TNF-a levels at 4, 24h were (221 ± 31) U/L, (181 ±39) U/L, (0.264 ±0.052) ng/ml and (0.257 ±0.071) ng/ml in treatment group, respectively; which were significantly lower than (272 ±32) U/L, (227 ±30) U/L, (0. 372 ±0.047) ng/ml and (0.422 ±0.026) ng/ml in the control group (P<0.05). The incidence of pancreatitis in proton pump inhibitors group was 1.6%, which was significantly lower than that in control group (5.6% , P = 0. 04) . Conclusions Combination of proton pump inhibitors and octreotide could effectively decrease the incidence of post-ERCP hyperamylasemia and pancreatitis.

The acupuncture prescriptions of IBS-D were selected and statistically analyzed, and a database was established. IBM SPSS 25.0 and clintine 12.0 were used to cluster and correlate the acupuncture point prescriptions.Results:A total of 190 literatures and 215 acupuncture prescriptions were included, including 75 acupoints, among which the most commonly used acupoints were Tianshu, Zusanli, Shangjuxu, Taichong, Guanyuan, Zhongwan, Sanyinjiao, Dachangshu, Shenque, Pishu. The most frequently used Meridian is Stomach Meridian of Foot-Yangming, St; The acupoints are mainly located in the lower limbs and the abdomen and Thorax; the most commonly used specific acupointis He-sea point; Zusanli and Tianshu both play an important role in treating IBS-D. Conclusion:Treating IBS-D with acupuncture and moxibustion follow the principles of choosing acupoints mainly according to Meridians, while selecting the acupoints with syndrome differentiation as the assistance, and also use the specific acupoints.to treat IBS-D.

A simple and accurate high-performance liquid chromatography (HPLC) coupled with diode array detector (DAD) and evaporative light scattering detector (ELSD) was established for the determination of six bioactive compounds in Zhenqi Fuzheng preparation (ZFP).The monitoring wavelengths were 254,275 and 328 nm.Under the optimum conditions,good separation was achieved,and the assay was fully validated in respect of precision,repeatability and accuracy.The proposed method was successfully applied to quantify the six ingredients in 31 batches of ZFP samples and evaluate the variation by hierarchical cluster analysis (HCA),which demonstrated significant variations on the content of these compounds in the samples from different manufacturers with different preparation procedures.The developed HPLC method can be used as a valid analytical method to evaluate the intrinsic quality of this preparation.

Objective To investigate the clinical features of a patient diagnosed with Jacobsen syndrome (JBS) and Paris-Trousseau syndrome (PTS) using chromosomal microarray analysis. Method A retrospective analysis including the patients' clinical manifestations, laboratory examination and genetic analysis was carried out and related literature were reviewed. Results A 14 month-old girl with global development retardation was reported. The patient can sit but cannot walk independently. The patient also presented hypsicephaly, ocular hypertelorism, palpebral ptosis, flat nasal bridge, sparse eyebrows, and speech delay. Gesell development scale showed that the patient was global development retarded with a development level of 40 weeks. No o bvious abnormality was found in EEG but the MRI showed cerebral white matter abnormality. This patient was also diagnosed with neonatal thrombocytopenia in other hospital. Genomic CNVs were detected in this girl, and a 15.7Mb loss was found in the 11q23.3q25 region that covers JBS and PTS region. Conclusions Patient diagnosed with JBS and PTS often present with craniofacial abnormalities, cerebral white matter abnormality and neonatal thrombocytopenia. Chromosomal microarray analysis can help diagnosis.

OBJECTIVETo determine bergapten's concentration in plasma and observe its pharmacokinetics in rats using a combined LC-MS/MS analytical method.

METHODBlood samples were separated on a Hypersil ODS column (4.6 mm x 250 mm, 5 mm) at a temperature of 30 degrees C, and mobile phase consisted of water and methanol (22.5: 77.5) at a flow rate of 0.8 mL x min(-1).

RESULTThe methodological study showed a good linear relationship of 8.12-162.4 g x L(-1) (r = 0.9999). The inner and inter-days relative standard deviations were both less than 10% , indicating legitimate precise and accuracy to the requirement of biological sample analysis.

CONCLUSIONThe method is suitable for in vivo quantitative analysis for bergapten due to its accuracy, sensitivity and specificity. The pharmacokinetic process in rats forms a two-compartment model with first-order absorption.

OBJECTIVE: To carry out genome-wide copy number variations (CNVs) analysis for a boy with autism by using single nucleotide polymorphism array (SNP array). METHODS: SNP array analysis was conducted for the boy and his parents, and the data was validated by real-time PCR. Correlation between the deleted genes and the phenotype was analyzed by reviewing the literature. RESULTS: The patient was found to carry a terminal deletion of 18q22.3q23 (7.1 Mb), which involved FBXO15, ZNF407, ZADH2, TSHZ1, MBP and ADNP2 genes. No pathogenic CNVs were found in the parents. Comparison of the patient with cases reported in the literature suggested that the ZNF407 gene probably accounts for the autistic phenotype in these patients. CONCLUSION The autistic phenotype of the patient may be attributed to the 18q deletion, for which ZNF407 may be a critical candidate. SNP array has provided an useful tool for the study of molecular mechanism underlying autism.

Electroacupuncture treatment of primary insomnia is widely used and with confirmed efficacy. The factors influencing the therapeutic effect of electroacupuncture include waveform selection, treatment frequency, stimulation intensity, stimulation time and acupoint selection. The mechanism of electroacupuncture in treating this disease mainly includes regulating the levels of excitatory neurotransmitters, γ-aminobutyric acid, melatonin and interleukin cytokines.
